About 17 years ago, Christie Brinkley did a Prell shampoo commercial. It was fantastic!! She (or someone) held her hair in a ponytail at the top of her head and then let it drop over her face. I believe the drop was filmed in slow motion.

Ivory also had a couple of great commercials circa 1989-90. Blonde woman with young daughter in a field of daisies. Close-up slow motion shots of the sunlit blonde hair blowing in a gentle breeze. It was like watching an explosion of silk!!!
